Homework Assignment-1Topics: Functions, Dictionary, ImportProblem description: Write a python application to simulate an online clothing system. Thepurpose of this assignment is to gain experience in Python dictionary structure, create basicPython functions and import a module.Design solution: The template file contains a list of clothes item sold, each item in the listcontains the item id, name of the item and the prices. The program will generate an items_dictwhere each key is the item id of the cloth and the values will be a list of item name and priceinformation. A customer will be presented with a main menu with 4 different options: displayall items, add an item to cart, checkout and exit the program. A customer can buy an item byentering the ID of the item. This program implements a dictionary called cart, where each key isthe item id and the values are the list of name, price and quantity that user chooses topurchase. The program keeps repeating by displaying the main menu to…

Data structures concatenate_dict(dict_list:list)->dict This function will be given a single parameter known as the Dictionary List. Your job is to combine all the dictionaries found in the dictionary list into a single dictionary and return it. There are two rules for adding values to the dictionary: 1. You must add key-value pairs to the dictionary in the same order they are found in the Dictionary List. 2. If the key already exists, it cannot be overwritten. In other words, if two or more dictionaries have the same key, the key to be added cannot be overwritten by the subsequent dictionaries.   Example: Dictionary List: [{'Z': 6, 'k': 10, 'w': 3, 'I': 8, 'Y': 5}, {'Y': 1, 'Z': 4}, {'X': 2, 'L': 5}]
Expected: {'Z': 6, 'k': 10, 'w': 3, 'I': 8, 'Y': 5, 'X': 2, 'L': 5} Dictionary List: [{'z': 0}, {'z': 7}]
Expected: {'z': 0} Dictionary List: [{'b': 7}, {'b': 10, 'A': 8, 'Z': 2, 'V': 1}]
Expected: {'b': 7, 'A': 8, 'Z': 2, 'V': 1}

Phyton: Program 6: Write a program that allows the user to add data from files or by hand.  The user may add more data whenever they want.  The print also allows the user to display the data and to print the statistics.  The data is store in a list.  It’s easier if you make the list global so that other functions can access it. You should have the following functions: ·        add_from_file() – prompts the user for a file and add the data from it. ·        add_by_hand() – prompts the user to enter data until user type a negative number. ·        print_stats() – print the stats (min, max, mean, sum). You may use the built-in functions. Handling errors such as whether the input file exist is extra credit. To print a 10-column table, you can use the code below:    for i in range(len(data)):       print(f"{data[i]:3}", end="")       if (i+1)%10==0:          print()    print()   Sample run: Choose an action   1) add data from a file   2) add data by hand   3) print stats   4)…

Data structures dict_from_string(dict_str:str)->dict This function will be given a single parameter, a string representing a dictionary. Your job is to convert the string into an actual dictionary and return the dictionary. Make sure all key-value pairs in the string exist in the newly created dictionary. The string will contain only numbers or single letters as key values pairs. Make sure all letters are kept as strings and all numbers are converted to integers in the newly created dictionary. Example: String Input: '{9: 'V', 'G': 0, 'M': 9, 'u': 3, 2: 'o', 8: 'u', 'q': 9, 'D': 1}'

Overview This is a review assignment where you will use multiple tools you have picked up so far throughout the course. If you're confused about how to do something make sure you look back at earlier assignments. In this program you will start by declaring an empty dictionary named population_dict. Then you will use a while-loop to prompt a user for a series of cities and their populations, storing the input in population_dict). After this you will prompt the user to decide what is the maximum population for a city to be considers a small down. Finally, you will open a file called populationdata.txt where you will write the results. Expected Output Example of standard out (the console): What is next city? (enter q to quit) Long Beach What is the population of Long Beach? 362000 What is next city? (enter q to quit) Los Angeles What is the population of Los Angeles? 382000000 What is next city? (enter q to quit) San Diego What is the population of San Diego? 136000000 What is next city?…

Program One: Basics Pizza1.py You do NOT need to use functions or a restart feature. You DO need comments! • This program calculates the total cost of buying a Pizza, and creates an invoice with prices for all the ingredients and the final total. • Your program should ask the user to input the size of the pizza and all the add-ons the user wants. • Include validation and basic exception handling. Accept the appropriate letter response in upper or lower case. • The program must calculate the total price of the pizza based on the size and the add-ons. You will have all the add-on prices in your code since the user does not get to choose what to pay. • Display the output as shown, controlling for the number of decimal places, $ sign and alignment. • Run more than once to test all the pizza options. I will be testing your program! Pizza2.py You need to copy Pizza1.py and make the following changes: 1. Using the MIPO model, rewrite your program so that a Main() function controls the program…

Word IndexWrite a python program that reads the contents of a text file. The program should create a dictionary inwhich the key-value pairs are described as follows:Key. The keys are the individual words found in the file.576Values. Each value is a list that contains the line numbers in the file where the word (thekey) is found.For example, suppose the word “robot” is found in lines 7, 18, 94, and 138. The dictionarywould contain an element in which the key was the string “robot”, and the value was a listcontaining the numbers 7, 18, 94, and 138.Once the dictionary is built, the program should create another text file, known as a word index,listing the contents of the dictionary. The word index file should contain an alphabetical listingof the words that are stored as keys in the dictionary, along with the line numbers where thewords appear in the original file. Figure 9-1 shows an example of an original text file(Kennedy.txt) and its index file (index.txt

C++ Write a program that will allow a user to enter students into a database. The student information should include full name, student ID, GPA and status. The program should allow delete any student based on student ID. You may not use a vecto or an array only the list function.

This assignment requires you to create a dictionary by reading the text file. Text file name: LightningP Text file contents: Stamkos3538Maroon2933Point5055Kucherov5565Killorn3340 The dictionary should have player names for the keys. The value for each key must be a two-element list holding the player's goals and assists, respectively. Start with an empty dictionary. Then, use a loop to cycle through the text file and add key-value pairs to the dictionary. Close the text file and process the dictionary to print the stats and determine the top scorer as before. Printing the stats for each player is the most challenging part of this program. The required output should be the same well-formatted table as below: PLAYER COLUMN: 10 characters wide and left-aligned. GOALS COLUMN: 6 characters wide and centered. ASSISTS COLUMN: 8 characters wide and centered. TOTAL COLUMN: 6 characters wide and centered. Example output:

Create an application to keep track of a list of students and their grades in a data structures course using a binary search tree.• Create a class called student that contains 2 data members: name and grade and then create a binary search tree of objects of this class. Make sure you validate the grade (A through F, and ? for in-progress grades).• Create a menu that has the following options:o Add a student -- add the student if he/she is not already in the classo Remove a student -- display “Not Found” error message if the student is not in the class.o Update the grade -- display “Not Found” error message if the student is not in the class.o Display class roster The program should use the binary tree definition. Please list all main, cpp, and hpp files. There must be a Student class, with Student.hpp and Student.cpp files. Do not use structures.
